KITCHEN-RANGE VJATIER HEATER.

Application filed. May 10, 1923. Serial No. 638,119.

To all whom 2'25 may concern:

a subject of the King of Sweden, and resident of Ostra Forstadsgatan 10C, Malmo,

in the Kingdom of Sweden, have invented certain new and usefulImprovements in KitchenRange Water Heaters, of which the following is aspecification, reference being had therein to the accompanying drawing.

This invention relates to improvements in kitchen-range water-heaterscomprising a box-like closed boiler extending behind the fire-place andfor a greater or shorter distance above the same and under thefire-place and the oven.

In the accompanying drawing is shown a kitchen-range provided with awater-heater according to the present invention. Figure 1 is a verticalsection on the line A-B of Figure 2. Figure 2 is a plan of the range.Figure 3 is a vertical section on the line C-D of Figure 2.

The water-heater comprises the horizontal boiler portion 1 known fromprior constructions and extending under the fire-place 6 and the oven,further the boiler portion 2 forming the back wall of the fire-place andthe ash-pit respectively, and finally the hori zontal boiler portion 3forming a roof over a portion of the fire-place and extending closeunder the fire-hearth. The said boiler portions are here joined with oneanother as usual so as to form a single closed boiler which is connectedwith a piping at 4 and 5.

For the utilizing of the heat of the escaping flue-gases to the greatestpossible extent the lower boiler portion 1 has been provided, accordingto this invention, on oneside of the fire-place 6 with a portion 7U-shaped in vertical section and having its legs turned upwardly, andthe upper boiler portion 3 has a corresponding U-shaped portion 8 withits legs turned downwardly, the said U-shaped portions alternating witheach other but leaving a free passage to the flue-gases above and underand between their legs, so that a zigzag-shaped flue is provided whichconnects the fire-place with the ordinary chamber 9 located under thelower boiler portion 1 and communicating with the flue-mouth. As is tobe seen from the drawing the U- shaped boiler portions are constructedas water-chambers communicating with the other portion of the boiler.Further, the lower boiler portion is, according to this formofembodiment, provided with an as- Be it known that I, PER OLorPErrEnsoN,

cending boiler portion 10 constructed as a water-chamber and forming thewall of the fire-place towards the oven and communicating with the rearboiler portion. The boiler portion 10 forms the fire-bridge of thefire-place towards the oven. Between the boiler portion 10 and the oventhere is a space 11 forming the continuation of the ordinary flues 12 tolet and 15, 9, 14: respectively. Consequently, the oven is touched bythe flue gases even on its fourth side.

The communication between the lines and the chimney-flue is produced bymeans of a rear flue 16 (Figs. 1 and 2) arranged in such a manner as tojoin the space 11 on the whole height of same or for a greater portionthereof and passing without sharp edges or angles into a square (orround) outlet turned upwardly. By means of the said rear flue theflue-mouth is thus converted from a long and narrow one in verticaldirection into a shape in the horizontal plan corresponding to the crosssection of the chimneyflue. By this arrangement the formation ofair-pockets injurious to the draught is prevented in the connectionbetween the kitchen-range and the chimney.

By the arrangement described above the heating-surface of the boiler isgreatly increased whereby the heat of the escaping flue-gases is betterutilized than hitherto, the capacity of the boiler being increasedcorrespondingly.

The kitchen-range itself may be arrangedin different manners as todamper, oven and the like, independently of this invention.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. Kitchen-range watenheaters comprising a closed boiler located at theside of the kitchen-range and extending behind the fireplace and partlyabove the same and under the fireplace and the oven, said boiler beingprovided, laterally of the fireplace and be tween the outer wall and thefire-place, with a portion U-shaped in vertical section and having itslegs turned upwardly and with a corresponding U-shaped portion havingits legs turned downwardly, the said lJ-shaped portions alternating witheach other but leaving a free passage to the flue-gases above and underand between the legs, so that a zigzag-shaped flue is provided which connects the fire-place with a passage located under the boiler andcommunicating with the flue-mouth.

2. In the water-heater as set forth in claim 1 the boiler being providedwith an ascend ing portion between the fire-place and oven andconstructed as a water-chamber.

3. A form of the water-heater as set forth in claim 2, a space beingprovided between the oven and the wall of the fire-place facing theoven, said space connecting a flue passing as usual under the oven withthe flue-mouth.

4. A form of the water-heater as set forth in claim 3, a rear fluecommunicating with said space and extending downwardly so as 15 to jointhe space on the whole height of same and gradually passing into anupwardly turned outlet.

In, witness whereof, I have hereunto signed my name.
